The Harvard Medical School published this video as part of their blog describing the overuse and misuse of mammography. The blog states:

They [JAMA Insights article co-authors Keating and Pace*] further point out that the USPSTF [U.S. Preventive Services Task Force] reiterated its recommendation in 2016 and that the American Cancer Society joined the task force in 2015 in advocating less routine use of mammography and a more individualized approach to screening.
“One of the greatest harms is overdiagnosis, which can subject some women to harmful treatment without any benefit,” Pace said. “Additionally, high rates of false positives and unnecessary biopsies should be considered as likely outcomes of breast cancer screening.”

Personally, I use thermography. It, too, is criticized as producing too many false positives but it doesn't expose patients to radiation so they can be done frequently and checked against a baseline. Those false positives, in my mind, are Qi Stagnation or Blood Stasis and can be treated with massage and acupuncture.

It baffles me that they end by saying that doctors know best. What physician has the time to spend counseling a patient or has the skill to do it?
